All thermal imagers need sufficient warm-up time for the most accurate temperature measurements and the best image quality. This time can often vary by model and by environmental conditions. Although most imagers are fully warmed up in 3-5 minutes, it is always best to wait a minimum of 10 minutes if the most accurate temperature measurement is important to your application. When you move the imager between environments with large differences in ambient temperature, more adjustment time can be required.
The imager includes a calibration on-demand feature that causes a calibration event to occur when you press the power button once briefly during operation. This feature provides the best accuracy and avoids disruption of a timing-sensitive image capture by the next automatic calibration.
Otherwise, the automatic calibration system will be more frequent during first start-up of the imager. This timing will become less frequent the longer the imager is allowed to acclimate to ambient temperature. There is no manual function to adjust this.
